SPECIFICATION forming part of Letters Patent N 0. 740,954, dated October6, 1903.

I Application filed April 3, 1903. Serial No. 160,968. (No model.)

To all whom it may concern.-

Be it known that I, EZEKIELVAN NooRDEN, a citizen of the United States,residing at Boston, in the county of Sudolk and State ofMassachusetts,'have invented a new and useful Improvement in SwingingWindows, of which the following is a full, clear, and exact description,reference being had to the ace-oinpanying drawings, forming a part. ofthis specification, in explaining its nature.

My invention relates to an improvement in swinging windows, andespecially to that class of window where the sash is pivoted at itscenter to swing vertically in the frame.

My invention consists in providing the sash in awindow of this kind witha set of movable weather-strips to make it tight and secure along itstop and bottom edges, where they unite, respectively, with the head andsill of the frame. The weather-strips are in the nature of movableplates or guards that are made to be extended from the top and bottomrails of the sash when closed to unite with the head and sill of theframe, as before referred to, so closing the intermediate spaceotherwise left between them, but whichplates or guards can be withdrawnor made to dis appear when the sash is to be swung open.

the same in horizontal cross-section on the line 3 30f Fig. 1.

Referring to the drawings, A represents the window-frame, and B thewindow-sash. The sash is pivoted between the head and sill of the frameat thepoints a a, respectively, to swingin an upright vertical position.

Both

aremade, however,as represented, of sheet or rolled metal plate.Concealed in a housing in the grooves or recesses 19 b, formed,respectively, in the top and bottom rails of the sash, are the plates Z119 These plates extend in their respective grooves the full width of thesash and are adapted to be partially moved or extended therefrom to makeweatherproof jointure with the head and sill of the frame, respectively,thus protecting the top and bottom edges of the sash, which extendcontiguously therewith when the sash is closed, the plate 12 beingextended from the recess 1), in which it is contained, into acoinplementary recess a formed in the head of the frame, while the plateb contained in the recess b, is extended therefrom to lap over the edgea formed in the sill thereof.

The plates 11 b are connected to be simultaneously moved or extendedfrom the recess in which they are contained to make their separatejointures with the frame by means comprising the bars h b fixed to saidrespective plates; the links 5 b pivoted, respectively, to the ends ofthe bars b b at the points 19 b and the rotary disk b to the op-- positeedges of which the said links are respectively pivoted at the points b 5These connecting members, comprising the bars, links, and disks, arepreferably concealed, it is to be noted, in the hollow verticalextendingsash-bar B. They are hung supported, together with the plates or guardsb biwhich they serve to connect, upon a member taking the form of a key,the shank Z2 of which ex tends at one end through the stud b fastenedWithin the sash and in which the shank has bearing and is extended toconnect at its The turning of the key has the effect of turning therotary disk b and thereby of simultaneously controlling the movement ofthe plates 1) b in their relation to the frame. This effect is obtainedby reason of the fact that the links b I) being pivoted to the oppositeedges of the disk b are alternately projected or retracted as the diskis turned, and this motion is utilized for the purpose of projecting orretracting the plates 11* b projecting them so that they make theirweatherproof jointure with the head or sill of the frame, as beforereferred to, when the sash is closed or drawing them back into theirrecesses in the sash when it is desired to swing the sash open, the sizeof the disk, the length of the links and connecting bars, and the widthof the weatherproof forming plates or guards being so coordinated thatthis effect will be obtained when the disk is turned from a vertical toa horizontal position, or vice versa, and this by turning the key on theinside of the sash. And it is to be especially noted that thisadjustment of the weatherproof forming plates or guards is obtained withperfect harmony, the plates and their connecting members being sorelated. that they practically balance one another upon the shaft orbarrel of the key as a center as the rotary disk is turned, exceptingwhen the links are in line and the plates are extended to make theirjointure with the frame, (see Fig. 2,) when a perfectly straight draftis maintained. Besides this capability of the plates for reinforcing thesash by providing it with a weatherproof jointnre with the head and sillof the frame, they act also as a means for locking the sash when closed,and such means as can only be unlocked from inside the sash, for, asbefore said, the key by which these plates are primarily controlled isaccessible only from the inside of the sash.

The practical utility of a means like as I have described needs nospecial mention. It is simple, economical, and effective. It constitutesan independent means which does not in any way interfere with thepivotal or swinging adjustment of the sash. It can be applied forsecuring the weatherproof jointure and for looking a single sash, or itmay be applied to sashes arranged in series, the means being especiallycapable of simultaneous actuation when applied to a series of windows.Moreover, the means although best applied to the kind of window and inthe manner like as I have shown may well be applied to other kinds ofWindow and still be within the essence of my invention. Its applicationto a horizontally instead of the vertically swinging sash would ofcourse be an obvious expedient.

Having thus fully described my invention, I claim and desire to secureby Letters Patent 'of the United States 1. A window having a sashpivoted or hung to swing within the frame, movable plates or guardscarried by said sash and which are adapted either to be moved outwardfrom the edges thereof to make jointure with the frame when the sash isclosed in order to afford a weatherproof protection therefor, or beretracted into the sash to permit of its being turned open, and meansfor simultaneously actuating said plates or guards to assume theirrelative changes in position.

2. A window having a sash pivoted or hung to swing within the frame,movable plates or guards concealed within the sash-bars to the sashwhich are adapted either to be moved outwardly therefrom to unitewith'the frame so as to afford a weatherproof protection for the edgesof the sash that conjoin therewith when the sash is closed, or beretracted into the sash so as to permit of its turning upon meansadapted to be accessibly influenced from within the sash forsimultaneously actuating said plates or guards to assume their relativechanges in position.

3. A window having a sash pivoted or hung to swing within the frame,grooves or recesses formed in the top and bottom rails of said sashplates or guards contained within the said recesses and which areadapted either to be moved out therefrom to unite with the head and thesill of the frame respectively so as to afford a weatherproof protectionfor the top and bottom edges of the sash that conjoin therewith when thesash is closed, or be moved to be entirely contained within the saidrecesses to permit of the sash turning open, and means adapted tosimultaneously move said plates or guards whereby they may unite withthe frame as aforesaid or be retracted into the recesses or groovesformed in the sash.

4. A window having a pivoted sash, grooves or recesses formed in saidsash alongalternate edges thereof, plates or guards contained withinsaid grooves or recesses, and which are adapted to be partially movedout therefrom to conjoin with the corresponding edges of the frame, andmeans for simultaneously controlling said plates or guards to beextended partially from or retracted into the said grooves or recessesin which they are contained comprising links and a rotarydisk to theopposite edges of which the said links are pivoted, and means forcontrolling said rotary disk, substantially as and for the purposes setforth 5. A window having a sash pivoted to turn upright within theframe, grooves or recesses formedin the top and bottom rails of saidsash, plates or guards contained within said grooves or recesses, andwhich are adapted to be moved out partially therefrom, the upper of saidplates to enter a groove or recess formed along the head of the frame,the lower plates or guards to lap contiguously with an edge formed inthe sill thereof, and concealed means for simultaneously controllingsaid turned from inside the sash, substantially as plates or guards tobe partially extended described.

from or retracted into the grooves or recesses T T T in which they arecontained eomprising links, EZEKIEL VAL A OORDELT a rotary disk to theopposite edges of which said links are pivoted, and a shaft or keyengaging in the said disk and aceessibly to he Witnesses:
